Kristallstruktur des supramolekularen Silber(I)thiocyanate-Cyclam-Komplexes [Ag(SCN).(C10H24N4)1/2

Abstract

Colourless crystals of the 1,4,8,11-tetraazacyclotetradecane (cyclam) silver(1) thiocyanate complex [Ag(SCN).(C 10 H 24 N 4 ) 1/2 ] were obtained by diffusion of a solution of cyclam in ethanol into an aqueous solution of K[Ag(SCN) 2 ]. The crystals are tetragonal, space group P4 2 /n, Z=8, a=b=1256.0(4), c=1185.5(9) pm. The SCN groups act as μ 3 ligands, the S atoms of two SCN groups bridge two neighbouring Ag ions, which are only 297.5 pm apart, forming butterfly-like Ag 2 S 2 moieties, the N atoms of the SCN groups form bonds to Ag atoms of adjacent Ag 2 S 2 moieties
